1. Makinawa amagwiritsa ntchito quartz crucible, yomwe imatha kuponyera zitsulo zambiri pa kutentha kwakukulu kwa madigiri 2300, kuphatikizapo golidi, siliva, platinamu, palladium, ndi zina zotero.

2. Zodzikongoletsera zosungunuka ndi kuponyedwa zili pansi pa vacuum ndi argon pressure kuteteza zodzikongoletsera zanu zamtengo wapatali ku okosijeni. Imakwaniritsa kachulukidwe kwambiri, kuphatikizika kwambiri, pafupifupi yopanda porosity ndipo imafika pakuponyera m'mitsempha yopanda shrinkage.

3. Mapangidwe ang'onoang'ono, kukula kochepa. Zokwanira bwino pazojambula zazing'ono zodzikongoletsera ndi zodzikongoletsera zazing'ono.

4. Ndi dongosolo la PLC lolamulira, limapangitsa njira yoponyera kukhala yanzeru kwambiri. Kulondola kwa kayendetsedwe ka kutentha ndi kolondola ± 1 ° C.

5. Ndi ma alarm osiyanasiyana, makinawo amasiya kugwira ntchito nthawi yomweyo kuti ateteze ngati cholakwika chilichonse chinachitika.

6. Pampu yopangira vacuum yomangidwa, poyerekeza ndi makina ena pamsika, omwe ali akunja, osungira ndalama zambiri pamtengo wowonjezera wa mapampu a vacuum, malo ochepa.

7. Kuponyera kodziwikiratu, kuphatikizapo kutembenuka kwapang'onopang'ono kwa chipinda choponyera. Oblique crucible ndi gypsum nkhungu, pamene kusungunuka kwatha, chipinda choponyera chidzangozungulira, kotero kuti madzi achitsulo amalowa mu nkhungu ya gypsum. Izi zimangochitika zokha, sizifuna ntchito yopangidwa ndi anthu, kupulumutsa ndalama komanso kupulumutsa antchito.

8. 5 kW kupatsidwa ulemu jenereta kuti mwamsanga kufika kutentha kusungunuka.
